+### Documentation and API Differences from Vaul
 
 You can use original [Vaul documentation](https://vaul.emilkowal.ski/getting-started) for more information.
+
+Since vaul-base uses Base UI internally (instead of Radix UI), the following components are re-exported directly from [Base UI's Dialog](https://base-ui.com/react/components/dialog) and follow Base UI's Dialog API conventions:
+
+- `Drawer.Trigger`
+- `Drawer.Close`
+- `Drawer.Title`
+- `Drawer.Description`
+
+
+> **Note:** Base UI uses `render` prop instead of Radix's `asChild` for composition.
+
+
+For more details on Base UI's Dialog, see the [Base UI Dialog component](https://base-ui.com/react/components/dialog).
